Area = Length x Width Chemical dosage: pounds per day (lbs./day) = MGD x ppm x 8.34 lbs./gal. Circular area = Br2 (B.3.14) OR circular area = 0.785 x diameter (D)2 Circular volume = Width x Length x Height Circumference = 2Br (where B.3.14; r = radius) CT = Chlorine concentration (mg/L) x time (minutes)
Tank Volume (gallons) Detention time = Flow (gpm or gpd)

Flow rate (Q, ft.3/sec.) = Velocity (ft./sec.) X Area (ft.2)
Force = Pressure (psi) x Area (in.2)
Pounds per gallon (not water) = Specific Gravity x 8.34
flow (gpm) Specific capacity = Drawdown (ft.)
Q (flow in gpm) x H (feet head) Water horsepower = 3,960
